The 24% Federal Withholding Trap: Why Winners Owe Millions in April
When an American citizen or resident wins a major lottery jackpot exceeding $5,000, federal law requires lottery administrators to immediately withhold 24% for the Internal Revenue Service (IRS).
Any income exceeding $609,350 (Single) or $731,200 (Married Filing Jointly) falls squarely into the top federal marginal tax bracket of 37%. Since multimillion-dollar jackpots exceed this threshold almost immediately, the winner is responsible for the full 37% tax rate on the entire prize.
Result: On a $500 Million cash lump sum, the lottery withholds $120 Million (24%), but the winner still owes approximately $65 Million (the remaining 13%) when filing federal taxes the following April!
